I A further `olsiject of my invention is '4to prov-ide 'a unitary v'molded plastic ifi-ier bloclcfhavi-ng flier Wire attaching means Lformed integral therewith, the flier wires and/or a iiicr wire balancing'loop being attached to the block by crossing' or over? lapping the Wires in the vicinity of the 'body portion of the lblock. f

With these-aiid other objectsin view, 'which may `Abe incident Ito my improvements, the ini'- vention consists iin 'the parts and combinations 'to be 'hereinafter set forth and claimed, with iti-ie understanding y"that 2the several necessary elements,vc omprising vmy inventionl may be varied in construction, proportions and arrangement, Without departing 'from the .spirit and :scope oi the .appended Aclaims.

' .In orderto make. .my invention .more .clearly understooml have shown inthe accompanying drawings .means 4for .carrying .the .same into practical eiect, without limiting the improntements in their usefulzapplications .tothe ,fparticu- 'le-r constructions. rwhich .fon-the purpose of fe-x planation. 'fhave losen yinode :the .subject of tilliistration. Y Y s 'In l.the drawings: l 'Figure 1l .is an elevational wiew, :partly :in `section, v'sloot/ing my improved .flier :in operative positionionkabobbinspindle. Fig. .l fis-a top plan v iewiofk thei-lierj-wire suppresent invention, comprises essentially, a ieiyk l block in the form of a centrally apertured body memberhaving base and head portions, a-pe-` ripheral ier wire support member formed on the body of the block between the baser and head portions, and a iiier wire support adapted `to seat on the peripheral support. The iiier wire support member, which may be formed from metalr or other suitable material, is provided with a centralopening adapted to receive the head-portion of the block, and is also provided with a plurality of cut-out portions contiguous tothe central opening', designed to receive complementary lug members formed on the head portion. In assembling the flier, the flier wiresupport is placed on the head of the block, with the lug members extendingthrough the cut-outporticns, and thereafterwards upon relative rotational movement between the block and the support, the flier wire support is Vsecurely clamped to the block.- f

Referring to the drawings, and more particularly to Fig. 1, there is shown a flier arrangement associated witha bobbiny I mounted in operative -position on a ysuitable spindle 2, of a conventional winding machine. The bobbin is provided with a head member 3; and a centrally recessed portion 4 adapted 'to receive a ferrule lA having an aperture 6 through which the flier foot 'I is inserted in thev iiier block, designated generally by numeral 8, Vcomprising a centrally apertured body portion B and a head portionlll'. Between the base and the*v head portions, there is provided a peripheral flange I I adapted to form a seat for the iiier wire support member, as will be explained Vmore fully hereinafter. f Referring to Fig. 2,V the flier wire support, designated generally by numeral- I2, is of general rectangular shape andas here shown, is formed from metal. It will be understood that the support may be formed from other materials having the necessary rigidity and adapted for cutting and/or forming. The-support is provided with a central opening adapted to receive the head -I of the iiier block,l and-the body portion is-formed with a plurality of cut-out portions I3, designed to receive complementary lugs I4, formed on the head of the iiie'r block, as will be described more fully hereinafter. In order to maintain the arms of the flier wires in desired separated position, the support is provided with diagonally arranged grooves I5 at opposite ends thereof and depressed portions I6 betweenadjacent grooves. y I

As will be seen in Fig. 4, the free ends I'I of the support I2 are slotted as at I8, and are turned backwardly and 'inwardly upon themselves to form flier wire attaching means.` Each ofthe flier wires comprises a central block. engaging portion I9, having .arms 20, extending outwardly-:theiefrom ,Itwill be noted that Ythe wires are crossed or overlapped asiat 2|, and Athat arms areprged into'seatedposition inslotsv I Bgby reason 0f; #13eitnsion,..120;gl.1ilif issy' are, Seb-l- "l'y above the .plane off-its bodyv portion, f and the intermediate portions are separated by the stops I B, formed by pressing the material of the support downwardly below the plane of the body vportion of the support.

The ilier block (Fig. 5) designed for use with the support I2, comprises a centrally apertured body .9, having a head portion I0, and an olf-set foot 1 adapted for insertion through aperture 6 formed in the ferrule 5 of the bobbin I. The head portion of the block is provided with a plurality of spaced lugs or projections I4, and between the base andl head portions, the block is formed' with a pair of' stepped peripheral anges II and 22,' providing supports for the ier wire support member and the flier wires, respectively.

The flier is assembled by inserting the head portion I0 of the flier block through the central opening of the support I2, with lugs I4 coinciding with the cut-out portionsv I3. Thereafter"- wards, the block is rotated to bring the lugs to positions intermediate the cut-out portions, thus clamping the flier wire support and the ier block together. The design of the lugs, cut-out por tions and the width of the groove-between, the lower faces of the lugs and the upper face. of flange Il, are correlated with respect to the flier wire support whereby a snug frictional ntie-attained to securely clamp the parts together,Y

inserted in the central opening of the support,

and prior to rotation of the block or the support to lock the parts together. In the position shown, it will be seen that the lugs I4 are in the cut-out portions I3,which portions terminate in arcuate shaped ends 2,3 at greater radial distances from the center of the support than the peripheral portions 24 of the central opening in the support. The relative positions of the parts, after rotation of the block or =the support, is shown in Fig. ,3, It will be Seen that the lugs I4 now extend over arcuate portions 24 and, as indicated hereinabove, by reason of the design of the lugs, cutfoutv porev tions .and the "width of the groove between the lower faces ofthe lugs and flange Il, a snug frictional fit is'obtained.

Referring to Figs. 6. and 7,- thereA is showna modified form ofY flier, comprising' `a v unitary molded plastic block `and ier wire support. In the modircation, the ier, designated generally by numeral 25, is formed 'with a substantiallyrec-` tangular shaped flier wire supportl 26, having inwardly turned end portions 2l, which are slotted as at 28, to receive Vthe arms of the flier wires. The central body portion 29 of the flierl is formed with a head portion 311 and an eccentric foot member 3l. As will be seen in Fig. "7, the body portion of the er isformed with a vperiph? eral ilange 32 having an enlarged. portion. 33,V

is to balance out centrifugal forces which are generated when the block is rotated, thereby providing a substantially uniform tension on the yarn.

The flier wire support is further provided with integral lugs or projections 34 designed to serve as flier wire fastening or retaining members. In attaching a wire to the support, the wire is looped around one of the lugs 34, as shown, with the arms over-lapped or crossed as at 35, portions of the arms outwardly from the overlap being seated in the slotted portions 28 of the support. By reason of the tension developed in the wire after it is looped about one of the lugs, as above described, the arms are forcibly urged into seated position within the slots of the inturned end p0rtions. Vertical movement of the arms with respect to the support is prevented by the inturned ends and by the oblong shaped tops 36 of the projections 34.

The flier structure shown in Fig. 6 is intended for use with double flier wires, that is to say, with two arms extending outwardly on opposite sides of the support, or with a single Iwire. When used with a single wire, as shown, a balancing member in the form of a loop 37 is attached to the lug which would normally receive the second wire. By means of the loop 371 the centrifugal forces generated by the single wire are balanced out when the block is rotated, thus providing uniform tension on the yarn.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth by way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, Without departing from the spirit of the invention or exceeding the scope of the appended claims.
